A friend of mine is planning to have a go at some cyanotype printing, but he's a little unsure of which material to use for the negative.
He's conducted a lot of research, but the source material is either old books or youtube videos, none of which go into much detail about the process of making the negative itself.
His plan so far is to produce a source image, converts it to a negative and then print onto acetate at the desired size (6" x 4" most likely), then print from that.
The intention is to only work in black and white, and to print using a laser printer onto the acetate. The printer in question prints at 1200 dpi on A4 sheets.
Is it likely that 1200 dpi would be a high enough resolution to produce a suitable negative to print from?
I'd be interested to hear from anybody who has done cyanotype printing in the past to find out their perspectives on it.
